<p>PURPOSE:To smooth the move of a cassette holder by composing a guide member so as to reduce the press of a cassette tape by a pressing member in the transition section in the moving direction from the horizontal motion of the horizontal member of the holding member of the cassette tape to the vertical motion or reverse direction. CONSTITUTION:Prior to the insertion of a cassette, the space of the guide wall 24 of a side face plate 17 with a pressing member 20 is made slightly larger and the guide pin B23 of the member 20 is engaged with the guide groove B25 of the side face plate 17 via the angular hole 27 provided on the side wall 15 of a cassette holder 1. The angular hole 27 and guide groove 25 have enough gap with the guide pin 23 and the pressing member 20 has the space rotatable within a constant range. In the case of inserting the cassette, a spring force is not loaded on the cassette until a roller 22 abuts the guide wall 24, since the cassette comes in by pushing up a sheet spring 21 and the pressing member 20 is rotated, and after the abutment the spring force is loaded thereon.</p> |
